Description

Technical Field

[0001] This utility model relates to the field of motor fan cover technology, and in particular to a motor fan cover blocking component. Background Technology

[0002] During the operation of an electric motor, its internal components generate a large amount of heat due to high-speed rotation. To ensure the normal operation and service life of the motor, a shroud is needed to protect it from heat. The shroud not only provides physical protection to the motor and prevents external debris from entering, but also needs to achieve efficient heat dissipation through a reasonable structural design. As a key component, the filter cover plays a dual role in blocking dust and debris and ensuring air circulation. Therefore, the rationality of its structural design is crucial to the operating status of the motor.

[0003] In the existing technology, the wind shield blocking components of motors usually adopt a more traditional mechanical structure. The filter cover is mostly fixedly installed inside the housing, for example, by welding, bolting and other methods to form a rigid connection with the housing. This structure can meet the basic protection requirements to a certain extent, but it relies on specific tools during installation and disassembly, and the fixed connection method also makes the relative position between the filter cover and the housing fixed.

[0004] However, due to the fixed installation method of the filter cover in the existing technology, the process of disassembling and cleaning the filter cover is extremely inconvenient. When the filter cover accumulates dust and debris due to long-term use, the operator needs to use tools to disassemble the complex fasteners. This is not only time-consuming and laborious, but also causes wear and tear on the parts due to frequent disassembly. As a result, it is difficult for the operator to clean the filter cover regularly. This directly leads to a gradual decrease in the filtration effect of the filter cover, making it easier for dust and debris to enter the motor, thereby affecting the motor's heat dissipation efficiency and reducing the service life of the motor. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a motor shroud blocking assembly, which aims to improve the problem of inconvenient disassembly and cleaning of the filter cover in existing shroud blocking assemblies, thus reducing the service life of the motor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor shroud blocking assembly, comprising a motor body and a housing, wherein a filter cover is disposed inside the housing, a connecting cylinder is fixedly connected inside the housing, a snap-fit ​​assembly is disposed inside the connecting cylinder, the snap-fit ​​assembly is used for disassembling and cleaning the filter cover, a sliding assembly is disposed on the outer wall of the filter cover, the sliding assembly is used for installing the filter cover, the snap-fit ​​assembly includes a limiting member, the limiting member is slidably connected to the inner wall of the connecting cylinder, a locking rod is fixedly connected inside the limiting member, a spring is sleeved on the outer wall of the locking rod, a limiting groove is formed inside the connecting cylinder, and the outer wall of the limiting member is slidably connected to the inner wall of the limiting groove.

[0007] Furthermore, the sliding assembly includes a docking block, one side of the outer wall of the docking block is fixedly connected to the outer wall of the filter cover, a docking groove is provided inside the cover, and the outer wall of the docking block is slidably connected to the inner wall of the docking groove.

[0008] Furthermore, a wing nut is provided on the outer wall of the motor body, a bolt is fixedly connected to one side of the outer wall of the wing nut, and a rubber gasket is fixedly connected to one side of the outer wall of the wing nut.

[0009] Furthermore, a sliding groove is provided inside the motor body, and an installation notch is provided inside the cover.

[0010] Furthermore, a slider is fixedly connected to the inner wall of the cover, and the slider is slidably connected to the inner wall of the groove.

[0011] Furthermore, the housing has heat dissipation holes inside, which are distributed in a ring on the outside of the motor body.

[0012] Furthermore, the filter cover has a locking hole inside, which is used to engage with the locking rod.

[0013] Furthermore, the outer wall of the bolt is threadedly connected to the inner wall of the mounting notch.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pulling the locking rod outward, the limiting component can be moved until the locking rod can disengage from the locking hole of the filter cover, thereby releasing the lock on the filter cover and realizing convenient disassembly and cleaning of the filter cover. After cleaning, the connecting block is fully inserted into the connecting groove, and then the locking rod is released. At this time, through the elastic action of the spring, the locking rod is driven to engage with the locking hole, thereby realizing the quick installation of the filter cover. This design facilitates regular cleaning of the filter cover, ensuring the filtration effect and greatly extending the service life of the motor.

[0016] 2. In this utility model, the heat generated by the motor during operation can be effectively discharged through the heat dissipation holes. The initial fitting of the cover can be achieved by the sliding setting of the slider and the slide groove. Then, the threaded connection of the bolt and the installation notch, combined with the rotation of the wing nut, makes the rubber pad tightly fit against the outer wall of the motor, thereby realizing the convenient installation and fixing of the cover, thus reducing the installation steps and time cost of the cover.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 4This utility model provides an embodiment of a motor wind shield blocking assembly, including a motor body 1 and a housing 2. A filter cover 7 is provided inside the housing 2, and a connecting cylinder 3 is fixedly connected inside the housing 2. A snap-fit ​​assembly is provided inside the connecting cylinder 3 for disassembling and cleaning the filter cover 7. A sliding assembly is provided on the outer wall of the filter cover 7 for installing the filter cover 7. The snap-fit ​​assembly includes a limiting member 9, which is slidably connected to the inner wall of the connecting cylinder 3. A locking rod 8 is fixedly connected inside the limiting member 9, and a spring 11 is sleeved on the outer wall of the locking rod 8. A limiting groove 10 is opened inside the connecting cylinder 3, and the outer wall of the limiting member 9 is slidably connected to the inner wall of the limiting groove 10. A locking hole 18 is opened inside the filter cover 7 for locking with the locking rod 8. The sliding assembly includes a docking block 12, one side of the outer wall of the docking block 12 is fixedly connected to the outer wall of the filter cover 7, and a docking groove 13 is opened inside the housing 2. The outer wall of the docking block 12 is slidably connected to the inner wall of the docking groove 13.

[0026] Specifically, the connecting cylinder 3, fixedly connected inside the housing 2, provides a stable mounting carrier for the snap-fit ​​assembly, enabling precise positioning of the snap-fit ​​assembly within the housing 2. The limiting member 9 is slidably connected to the inner wall of the connecting cylinder 3, and can reciprocate along the axial direction of the connecting cylinder 3, thereby driving the snap-fit ​​rod 8 to move synchronously. The snap-fit ​​rod 8, fixedly connected inside the limiting member 9, forms a snap-fit ​​engagement with the snap-fit ​​hole 18 of the filter cover 7. When the snap-fit ​​rod 8 is inserted into the snap-fit ​​hole 18, it restricts the axial movement of the filter cover 7 within the housing 2. The spring 11 sleeved on the outer wall of the snap-fit ​​rod 8 undergoes compression deformation when the snap-fit ​​rod 8 is subjected to force and moves outward. When the external force is removed, the spring 11 pushes the snap-fit ​​rod 8 to automatically insert into the snap-fit ​​hole 18 through elastic restoring force, achieving automatic locking of the filter cover 7. The limiting groove 10 inside the connecting cylinder 3 provides a guide track for the sliding of the limiting member 9, while also limiting the radial displacement of the limiting member 9, ensuring that the snap-fit ​​rod 8 always remains coaxially aligned with the snap-fit ​​hole 18. The locking hole 18 inside the filter cover 7 matches the end shape of the locking rod 8, forming a tight locking structure to prevent the filter cover 7 from loosening due to vibration during the operation of the motor body 1. The mating block 12 in the sliding assembly is fixedly connected to the outer wall of the filter cover 7 and forms a sliding guide structure with the mating groove 13 inside the cover 2. When the filter cover 7 is inserted into the cover 2, the mating block 12 slides along the mating groove 13 to ensure that the filter cover 7 accurately reaches the installation position. At the same time, the cooperation between the mating block 12 and the mating groove 13 can restrict the circumferential rotation of the filter cover 7 and ensure that the locking hole 18 and the locking rod 8 are precisely aligned.

[0027] Reference Figure 2 and Figure 5The outer wall of the motor body 1 is provided with a wing nut 4, a bolt 6 is fixedly connected to one side of the outer wall of the wing nut 4, and a rubber pad 17 is fixedly connected to one side of the outer wall of the wing nut 4. The motor body 1 has a sliding groove 14 inside, the cover 2 has an installation notch 16 inside, a slider 15 is fixedly connected to the inner wall of the cover 2, the slider 15 is slidably connected to the inner wall of the sliding groove 14, and heat dissipation holes 5 are provided inside the cover 2, which are distributed in a ring on the outer side of the motor body 1.

[0028] Specifically, the wing-shaped nut 4 on the outer wall of the motor body 1 adopts a double-wing structure design, which is easy for operators to tighten by hand without additional tools. The bolt 6 is fixedly connected to one side of the wing-shaped nut 4 and forms a threaded connection with the mounting notch 16 of the cover 2. By rotating the wing-shaped nut 4, the bolt 6 can be screwed in or out along the threaded hole of the mounting notch 16, thereby fixing or removing the cover 2 from the motor body 1. The rubber gasket 17 fixedly connected to the other side of the wing-shaped nut 4 is made of elastic material. When the bolt 6 is tightened, the rubber gasket 17 is squeezed and adhered to the outer wall of the motor body 1, which increases the friction of the contact surface to prevent the cover 2 from loosening. At the same time, the rubber gasket 17 can fill the gap and play a role in sealing and dust prevention. The sliding groove 14 inside the motor body 1 and the slider 15 fixedly connected to the inner wall of the cover 2 form a sliding fit structure. During installation, the slider 15 slides along the sliding groove 14, providing precise guidance for the fitting of the cover 2 and ensuring that the cover 2 can be stably installed on the outside of the motor body 1. At the same time, the fit between the sliding groove 14 and the slider 15 can restrict the circumferential rotation of the cover 2, ensuring that the mounting notch 16 and the bolt 6 are precisely aligned. The mounting notch 16 inside the cover 2 provides operating space for the bolt 6 to be inserted and tightened, allowing the bolt 6 to pass smoothly through the cover 2 and connect to the motor body 1. The heat dissipation holes 5 inside the cover 2 are evenly distributed in a ring on the outside of the motor body 1. The heat generated by the motor body 1 during operation is discharged through the heat dissipation holes 5 through air convection. The ring-shaped distribution of the heat dissipation holes 5 can ensure uniform circumferential heat dissipation of the motor body 1, avoid local overheating, and thus maintain the normal operating temperature of the motor body 1.

[0029] Working principle: When using the wind shield blocking assembly, first align the slider 15 on the inner wall of the cover 2 with the groove 14 on the outer wall of the motor body 1, and slowly slide the cover 2 along the direction of the groove 14 so that the cover 2 is initially fitted onto the outside of the motor body 1. After the fitting is completed, insert the bolt 6 into the mounting notch 16, and then rotate the wing nut 4 to drive the bolt 6 to be screwed into the inner wall of the mounting notch 16 until the rubber pad 17 of the wing nut 4 is tightly fitted against the outer wall of the motor body 1, thereby realizing the convenient installation of the cover 2.

[0030] When the filter cover 7 inside the housing 2 needs to be disassembled and cleaned, the locking rod 8 can be pulled outward, which will cause the locking rod 8 to move the limiting part 9. At the same time, the spring 11 on the outer wall of the locking rod 8 will be compressed and contracted. Through the setting of the limiting groove 10, it can be ensured that the locking rod 8 will not deviate during movement until the locking rod 8 can completely disengage from the locking hole 18 inside the filter cover 7, thereby releasing the locking of the filter cover 7 and realizing the convenient disassembly and cleaning of the filter cover 7. After the filter cover 7 is cleaned, the connecting block 12 on the outside of the filter cover 7 is aligned with the connecting groove 13 inside the housing 2 and inserted until the filter cover 7 is completely inserted into the housing 2. The locking rod 8 can then be released. At this time, through the elastic action of the spring 11, the locking rod 8 can be moved into the locking hole 18 until the locking rod 8 and the locking hole 18 are completely engaged, thereby realizing the installation of the filter cover 7.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
